> CONFIG proxy.config.http.cache.ignore_authentication INT 1
I just tried this one, but unfortunately ATS still does not revalidate. No > If-None-Match / If-Modified-Since headers in the log, cache MISS every time. *Actually it does work,* but I had to use it together with: CONFIG proxy.config.http.cache.required_headers INT 0 Probably because of the missing Cache-Control header. So thanks a lot Leif!
